First, you need to check the antifreeze. In general, a change of antifreeze every two years. Followed by oil, comes in the winter, it is timely to the oil pan, oil air compressor, and replaced with oil in winter; the transmission, transfer, differential, steering gear oil inside, and replaced in winter gear oil; wheel bearings after washing, low viscosity lubricating bearings.

Air conditioning

Highlights automotive air conditioning and refrigeration systems and winter maintenance are: monthly air conditioning and refrigeration systems start 2 to 3 times, every 10 minutes or so. You can choose to start the cooling system temperature is higher than 10 ℃, thereSunlightDay, in a moving way open for 10 minutes. To be reminded that many car air conditioner is equipped with a temperature control circuit, when the ambient temperature is below 10 ℃, will automatically cut off the electromagnetic clutch current air-conditioning compressor, the refrigeration system does not work, instead of cooling system failure.

Heater

Heater stop using a longer time, there will be failures, first try there is no hot air blower running any abnormal sound, duct patency. Sometimes the problem is encountered in the antifreeze heater pipes for long periods of flow, condensation blocked circulation line, although not affect traffic, but it is very troublesome to repair.

Windows

Below zero degrees Celsius in the winter environment should replace the glass of water freezing in the winter, or, more simply, in a glass of water by adding an appropriate proportion of alcohol can be achieved by lowering the freezing point, freezing purposes. Aging of rubber wiper blade is rigid and can not be used to ensure the safety of the best replacement.

Tire

Winter road surface friction coefficient low tire pressure is not too high, not too low, but more low outside temperature, tire pressure is too low, soft tires will accelerate the aging seriously. As the car has some camber positioning and high on both sides of the road in the middle of the characteristics of low tire wear different inside and outside, in order to ensure safety to reduce wear and tear, you should periodically replace the tire position.

Headlight

Blackened bulbs replaced as soon as possible, thus reducing the number of changing light bulbs in the winter. Winter, particularly in the rear-end accidents because of fog in winter frost prone, low visibility. So CHMSL is to work to protect the safety of winter driving.
